Barite
Barite is sulfate, BaSO₄. In the hand, it rates 3 to 3.5 on the Mohs scale, and it runs colorless and white. A non-metallic mineral that feels shockingly heavy for its look, bladed or tabular crystals with pearly cleavage flashes. Hydrothermal veins and sediments; notable: Morocco, China, Oklahoma (USA, barite roses), England.
The geology.
Barite carries the formula BaSO₄. It belongs to the orthorhombic system. The trade files it under sulfate.
It sits at 3 to 3.5 on the Mohs scale. The surface reads vitreous to pearly. Light behaviour is transparent to opaque. Specific gravity runs 4.3 to 4.6. The streak is white. It breaks with perfect basal cleavage.
A non-metallic mineral that feels shockingly heavy for its look, bladed or tabular crystals with pearly cleavage flashes.
Common cuts are bladed crystals, desert roses, golden blades on matrix or tumbled.
The origins.
Hydrothermal veins and sediments; notable: Morocco, China, Oklahoma (USA, barite roses), England.
On value, the database notes: common; fine blue blades are mid-range.
Traditional associations.
In energy work traditions, associated with steadiness during change.
Included for completeness. Tradition is worth knowing about, and it is worth keeping separate from the mineralogy.
Spotting the real thing.

| Looks like | How to tell them apart |
|---|---|
| Celestite | Nearly identical; celestite is slightly lighter and classic sky-blue geodes are celestite |
| Calcite | Calcite fizzes in vinegar and feels much lighter |
| Selenite | A fingernail scratches selenite; barite resists |
At-home tests.
These checks cost nothing. Daylight, a 10x loupe and a little patience are the whole kit for barite.
| Test | What you should see |
|---|---|
| Heft test | noticeably heavier than quartz of the same size (SG ~4.5) |
| Acid check | No fizz with vinegar |
| Scratch check | Knife scratches it |
Anything that scratches, burns or dissolves the piece is a lab job. Get it appraised rather than testing it apart.
Care & handling.
At 3 to 3.5 on the Mohs scale this is a soft material. Keep it as a display piece, store it apart from harder stones, and skip daily-wear settings.
It breaks with perfect basal cleavage, which is worth knowing before you set it or drop it.
Warm water and a soft cloth clean almost everything. Ultrasonic tanks, steamers and household cleaners are where pieces get ruined.

The physical record
The formula on record is BaSO₄. Crystal system: Orthorhombic. Specific gravity: 4.3 to 4.6. Streak: White. Cleavage and fracture: Perfect basal cleavage.
How it reaches the market
Hydrothermal veins and sediments; notable: Morocco, China, Oklahoma (USA, barite roses), England.
What it gets confused with
Celestite: Nearly identical; celestite is slightly lighter and classic sky-blue geodes are celestite. Calcite: Calcite fizzes in vinegar and feels much lighter. Selenite: A fingernail scratches selenite; barite resists.
What it is worth
Common; fine blue blades are mid-range.

Barite is the weighting agent in oil-drilling mud, most of the world's production is pumped down boreholes.
